INFORMATION
Please specify
1) Tank type, vertical or
horizontal
2) Storage capacity of foam
concentrate
3) Model number, size of
ratio controller with flow

4) Type of foam concentrate
to be used and percentage of induction
required.
APPLICATION
The Bladder Tank Foam Proportioning System utilises
the water pressure to inject foam concentrate into a
water supply and automatically proportions foam
concentrate over wide range of flow and pressure, with
very low pressure drop. This system does not require
concentrate supply pump.
SPECIFICATION
The Bladder Tank Foam Proportioning System are
available with vertical and horizontal bladder tanks.
The carbon steel tanks are designed and constructed
in accordance with ASME Code Section VIII for unfired
pressure vessels. The maximum working pressure is
12 Bar (175 psi) and factory tested for 18 Bar (261
psi). The vertical tank assembly is supported by a
continuous skirt with provision for anchoring. The
horizontal tanks are supported by two saddles welded
to the tank and drilled for anchoring. Tank is provided
with lifting lugs.
The system is supplied with pressure vessel, bladder,
fill and drain valve for water and foam concentrate,
ratio controller and vent valve. The ladder and sight
glass assembly is supplied as optional item on request.
PRINCIPAL OF OPERATION
The foam concentrate is to be filled into the bladder
very carefully to avoid rupture of the bladder. The
instructions for filling are provided with the equipment.
Once the main water flow is established and water
inlet and foam outlet valves are opened, the water
